Introduction

This Tome is a part of the project «Construction of substation 220 kV Lafarge».

This Tome presents technical solutions of implementation of the relay protection and automation systems with microprocessor-based devices for the next elements of substations 220 and 35 kV Lafarge:

- three-phase three windings transformers 220/35/6,6 kV;

- switchgear 35 kV.

The is also a list of relay protection and automation functions and supposed composition of microprocessor-based relay protection devices (ABB, Areva, General Electric, Siemens, NPP «EKRA») mounted at the elements of the substations 220 and 35 kV Lafarge, which are listed above.

Developed technical requirements for relay protection and automation devices are necessary and sufficient for realization all the technical solutions presented in this project.

1.1. According to specifications of technological connection with the electrical grid of OAO «UES FGC» from 29/12/2010, developed with usage of the application from 29/03/2010 № Исх-3-10/260 from ООО «Lafarge GEO» there will be construction of two single circuit high-voltage lines 220 kV Stany-Lafarge 1, 2 and the new substation 220 kV Lafarge which is necessary for the power supply of the cement plant.

Substation 220 kV Lafarge will be connected with the new power circuits of ОАО «UES FGC» in two points: the new feeders 220 kV of high-voltage lines 220 kV Stany-Lafarge 1, 2 at substation 220 kV Stany.
